The little ones have now been moved to tanks, give them a bit more growing room.
Here's a pic of the latest batch at one day old.
Wtb, Mature female/s or even a trio (1m, 2f) if anyone knows of any for sale locally??

Talking to the previous owner today, he was saying they can be quite prolific once they get started. Which I have certainly noticed.

Would like to get another mature female or two, would be nice to continue breeding them. Will be interesting to see how long these guys go between seasons.
I use slow running air stones in the fry and eggs tubs, doing 2-3 daily water changes on the tubs, refilling slowly (with water from the parents tank).
Their first few spawns temp was rather cool at 22.C and hatch time rather slow, taking 4-5 days. Then I turned the heat up hoping to speed up hatch time which it did but not by much. Once the temp hit 25.C (for the last 2 spawns) hatch time sped up dramatically to 2 days, although the fry didn't look as developed as the previous fry hatching over a longer period of time, although their growth rate may speed up, the egg casings/shells also seemed to break down quicker in the warmer water. They seem a little more delicate hatching sooner, so this may not be a good thing.
Anyway these are the tank stats
Temp 22-25.C
pH 7.4
GH 80 ppm
KH 40 ppm

The last 2 spawns have hatched way under developed, much more so then even the previous spawn, lost all of the last spawn and this one is looking no different. When they hatch they are just a ball with eyes and tail, pretty much the same as they are in the egg but the tail is sticking out, even then you need a torch to see them. Shortly after hatching they start dropping off one by one. :cry:
Any thoughts?
Previous fry are all doing well. :wink:

The thing that surprises me is the regulatity of this pair spawning !!
Admittedly I have only bred hopolos in outdoor plant raising ponds, but I never considered that they were as prolific as our common cories !
Your pair are producing some interesting stats
Keep us postd !!!

from memory some eggs wont even hatch if the conductivity is wrong. i heard about 100-200uS is about the benchmark for discus... could this be something u can look into?

I took a pic Monday, although it doesn't really show how much they have grown, I might try adding a ruler for the next pic, see how that goes.

Not sure about conductivity, but its something I'll be looking into. Do you have anymore information on conductivity at all?

The composition of the water is obviously important for fertility, egg hatching and fry development. But which factors are most important? Is it the concentration of calcium and magnesium ions (general hardness) which the article tended to downplay the importance of. Yet this was the only factor quoted in the article of proven importance. Sodium and chlorine concentrations (salinity)? Humic acids? Other chemicals??
Food for thought
Cheers

This little guy is just over 6 weeks old, he/she is one of the bigger ones from the first lot of fry. (I had the age wrong on the last 2 fry pic's, miss calculated somewhere along the way). :oops:
Hoplo 6 weeks 3 days from hatch.

Not a real bad photographer either :!:
Personally I have never seen a pictorial story like this on any fish on any forum by one person.
We have a pretty renouned record here on peppermint Ancistrus, but that was a collective effort by a number of members and we should thank everyone for their contibutions to that informative strand.
But this is a sole effort by our quiet little moderator. Tammy, you are a legand !
One little thing you didn't tell everyone was that you had run out of live food for the last couple of weeks, and was only five days of the good stuff that had them back spawning again. :wink: But those pics overshadow that little omission.
Keep up the excellant work. What is your next project :?:

The live food really seems to play a part, when I run out of live food they go longest between spawns. Coincidence, maybe?
Well looks like temp has been ruled out as the sole cause for the eggs hatching so early. Time to have a closer look at the water it self.
Here's a pic I managed to get showing eggs stuck to the males fins, with fresh eggs being quite sticky much the same as cory eggs, as the male has gone over the nest blowing more bubbles some of the freshly laid eggs have stuck to him. The female also had an egg stuck on her barbels.
